Press s to take a photo! Save the drawing by seeing inside, right clicking the list, and pressing export, you can then save it and import it from that same menu aswell. Press space to manually initiate drawing (after scanning) if you missed the drawing process! If you initiate a certain stage (scanning/drawing) manually, I reccomend you press the flag before you press something else. See notes and credits for quality settings.
This is a very high fidelity scanner with the right settings, set the fidelity variable to adjust the distance per scanpoint. The lower the better (but it can take ages if you set it too low!) 25 is a good balance, takes 5-10 mins, 50 for a test, takes 2 mins. Use 15 for high quality scans (30mins). Also, please use fidelity 25 for the example image of my fireplace!
